1. Which type of heat transfer, caused by uneven heating, moves air and water
1 answer:
Answer:
Convection
Explanation:
Convection is the transport of heat by a fluid like air or water.
Hot air is less dense than cold air, so hot air rises and cold air sinks.
In weather, convection refers to the vertical transfer of heat and moisture from the surface to a cooler area aloft.
Conduction is wrong. It involves the movement of heat by collision of molecules.
Radiation is wrong. It does not need a medium to transfer the heat.

The new pH is 7.69.
According to Hendersen Hasselbach equation;
The Henderson Hasselbalch equation is an approximate equation that shows the relationship between the pH or pOH of a solution and the pKa or pKb and the ratio of the concentrations of the dissociated chemical species. To calculate the pH of the buffer solution made by mixing salt and weak acid/base. It is used to calculate the pKa value. Prepare buffer solution of needed pH.
pH = pKa + log10 ([A–]/[HA])
Here, 100 mL of 0.10 m TRIS buffer pH 8.3
pka = 8.3
0.005 mol of TRIS.
∴
<em> </em>inverse log 0 =
Given; 3.0 ml of 1.0 m hcl.
pka = 8.3
0.003 mol of HCL.
Therefore, the new pH is 7.69.
